"Give you something to do next week." He didn't doubt that Stiles would find them all in the coming days, but he couldn't resist teasing his mate just a little bit.
All the sounds that Stiles made - Derek grinned as he listened to him whimper, and pressed slowly on the base of the plug again until he couldn't get it any deeper. "Can't wait until it's me either. Until it's my knot stretching you out, making you come -"
And then that impish streak of his mate's struck. It drove him mad sometimes, but now he could only grin as he listened to Stiles' request and lapped at the crown whenever it emerged from between his fingers.
"You know if you had a knot, I'd never get off you. You feel so fucking good now," he started as he reached for the lube on the bedside table and slicked up his fingers. "But with a knot, I could sit on your dick and make myself come until I ran dry, all because of how good your cock is." Smirking, he didn't move up so much as around, stopping only when his knees were braced against Stiles' biceps, and he still had a face full of his cock. Only now, Stiles had a front row seat to watch.
One hand flat on the bed to keep himself steady, he reached back, two fingers running around his rim before he began to ease them inside. "Can you see, baby? Got a good view? Gotta make sure you're hard enough to give me that fucking knot of yours." He moaned, thighs flexing as his fingers eased deeper.
"Fuck, want to talk about nice bodies? I want more of yours, all the time. Not a part of you that's going to remain untouched by me before the weekend's over."
